Hi, Just had my brakes replaced, and the shop (not dealer) told me I should have the following items done.
transmission fluid replaced
power steering fluid replaced
coolant replaced
brake fluid replaced
spark plugs replaced
belts replaced
fuel filter replaced
They based this on the fact that the car has never had any of these services done. the car still drives well and I want that to continue with no major repairs.

I would walk away from that place. The transmission fluid is "lifetime" fluid and really doesn't need a scheduled change.
Plugs are at something like 100k.
Sounds like they are just trying to sell you everything in the book.
Your best money will be spent at a reliable dealer and have them perform an inspection. Sure it will cost a couple bucks, but having a set of eyes that works on these cars all day long is priceless..
Once you get a pro opinion, either do what they say or look for an Indy to perform what you need.

- plugs at 5yrs or 100K
- fuel filter at 5yrs or 60K
- coolant at 15yrs or 150K (that is too long for my blood personally I change it every 3yrs)
- air filters at 4yrs or 60K (again too long for me)
- brake fluid flush every 2yrs
- charcoal cabin filters 5yrs or 60K
- belts are as needed
- and there is no power steering service under scheduled maint. unless the system is repaired or disassembled for some reason (W220's dont have the power steering filters like my other two older MBZ's)
- and trans service is also not "required" but I still get my differential and trans fluid/filter serviced and changed every 50K.... TX heat is killer on gear oils & fluids .....and I suffer from OCD.

All trannys should be serviced. There is no such thing as filled for life, most transmissions fail due to oil fluid breakdown, and 90% of the time the driver is not aware that the fluid has been overheated, this is when things go south.

Same maintenance schedule as mine except for the coolant (every 3 years) and I have followed that.

Transmission service would be first on my list. As stated above plugs and brake fluid are past due but not as critical as ATF/filter change. I did plugs and fuel filter at 80,000 and had no symptoms so could probably have gone another 20,000. Now with 89,000 I think my serpentine belt is the original; check yours for deterioration/cracks.

A dealer tech I know recommends the differential fluid too but admitted there is no published MB interval on that.

The transmission fluid is "lifetime" fluid and really doesn't need a scheduled change.

Liftetime means "new transmission at 150k".

Dealer is right, get everything done on the list, if everything has never been serviced add steering and differential fluid on the list.
It will be pricy, but it is all vital if you want to avoid problems in the future.

if you want to safe money you can do some of the services on the list by yourself.
I would recommend doing the spark plugs, it takes a lot of pricy time.
Power Steering Fluid is easy.

You should do these preventive maintenance items to avoid costly repair maintenance. Strongly recommend using MB products for transmission fluid and engine coolant. AutohauzAZ.com is a great source for parts.

IMHO, you can do all of these yourself. In order of increasing difficulty for a DIY (and to gain self confidence), they would be:

The encyclopedia on this forum, and the stickies on the W210 forum are a great source of information for DIY like these.

Replacement of engine coolant, transmission fluid and power steering can be done in increments. Trying to empty these systems can be done, but it is more labor intensive and probably not as much benefit as you would think.

BTW - The W220 shares the same transmission with the W210 class. The sealed for life debate is over in that older chasis forum. I had to put down my 400E due to a transmission failure just shy of 180,00 miles. Had rolled 120k miles on that car, and failed to servcie the transmission during my time of ownership. Never again will I lose a MB to neglect like that.
